Have you ever had to call a customer to apologize and refund their money because they bought a product on your website that had already been sold on Amazon?
When a company scales and starts selling across multiple channels (Own online store, Marketplaces, B2B, and physical store), inventory becomes a living hell. Updating stock manually by uploading CSV files once a day is no longer enough. If there's a sales spike, you sell products you don't have, your reputation plummets, and Marketplaces penalize you by suspending your account.
The Problem with Cheap 'Connectors'
There are €20/month plugins that promise to connect everything. The problem is they work in batches every 15 or 30 minutes. During Black Friday or strong campaigns, a 15-minute delay means dozens of erroneous orders. Furthermore, if your ERP is legacy or custom-built, those standard plugins simply cannot connect to it.
Our Solution: High-Frequency Cloud Middleware
At LANZAESTUDIO.ES we don't use commercial plugins. We deploy a custom Cloud Middleware (an intermediary 'brain') that communicates directly with the APIs of all your sales platforms and your management system (ERP).
- Millisecond Synchronization: If someone buys the last unit on your Shopify, our system notifies Amazon and your B2B system in under a second so the product appears as 'Out of Stock' everywhere.
- Custom Business Rules: We can program complex logic. For example: always reserve 5 units of safety stock exclusively for your VIP wholesale clients.
- Centralized Hub: You no longer have to log into 4 different dashboards to see what has sold. Everything flows through a single, clean, and controlled database.
The Real Impact on Your Company
- Zero Penalties: Amazon and other marketplaces will never block your account again for having a high cancellation rate due to out-of-stock items.
- Operational Peace of Mind: Your warehouse team stops doing panic manual inventories and blindly trusts what the system says.
- Immediate Scalability: If you want to open a new sales channel tomorrow (e.g., TikTok Shop), we just have to connect it to the central brain; the rest of the infrastructure is already prepared.
